AppUsage measures time spent on each app. See which apps to uninstall because you’re not using them! Accurate to less than a second on Android 1.6 and up. AppUsage will show you usage by time or number of launches for today, the last week, the last month, or since its installation. You can also check info like first launch and install date. This app uses virtually no battery power, as it only records when you change apps, not on a regular schedule.

See how much time you’re wasting on Angry Birds or Facebook, or know that you can uninstall that one app you forgot about and never used!
